And who is he that overcometh? (ti estin de o nikwn?). Not a mere rhetorical question ( 1 John 2:22 ), but an appeal to experience and fact. Note the present active articular participle (nikwn) like nikai (present active indicative in verse 1 John 4 ), "the one who keeps on conquering the world." See 1 Corinthians 15:57 for the same note of victory (niko) through Christ. See verse 1 John 5:1 for o pisteuwn (the one who believes) as here. Jesus is the Son of God (Ihsou estin o uio tou qeou). As in verse 1 John 1 save that here o uio tou qeou in place of Cristo and see both in 1 John 2:22 . Here there is sharp antithesis between "Jesus" (humanity) and "the Son of God" (deity) united in the one personality.
